LAS\SET TYPE CONTINUUM or LINE or SKYDIP Defines on which type of data the program is working. - LINE (or SPECTROSCOPY) (the default when entering LAS) selects Spectral Line data only, and the program prompt is LAS> (Line Analysis System). - CONTINUUM selects continuum drifts results only, and the program prompt changes to CAS> (Continuum Analysis System). - SKYDIP selects only skydips, and the prompt changes to SAS> In CONTINUUM mode, a continuum drift is treated as a spectrum would be in LINE mode. You can add drifts, subtract baseline, make gauss fits, change plotting scales etc... The current angular units is used in plots. SKYDIP mode has very limited capabiblities: only command REDUCE may be used to analyse the SKYDIP results.
